No attempt to get anything right, except the same kind of plot you are
creating. It works great for me! Using IDL 8.2.3 on Windows.

image = cgDemoData(7)
image = cgScaleVector(image, -200.0, 1500.)
map = cgMap('Equirectangular', Limit=[-90, -180, 90, 180])
image = Shift(image, 180, 0)
dims = Size(image, /Dimensions)
lons = cgScaleVector(Findgen(dims[0]), -180, 180)
lats = cgScaleVector(Findgen(dims[1]), -90, 90)
cgLoadCT, 0
pos = [0.1, 0.3, 0.9, 0.9]
map -> SetProperty, Position=pos
cgDisplay
cgImage, image, Position=pos, /Scale, /Save, $
XRange=[-180,180], YRange=[-90,90]
cgColorbar, Range=[Min(image), Max(image)], $
Position=[0.1, 0.1, 0.4 , 0.15]
map -> Draw
cgMap_Grid, /Box, Map=map
conColors = ['red6', 'grn6', 'yellow', 'blu6']
TVLCT, cgColor(conColors, /Triple), 1
cgContour, image, lons, lats, Levels=[500, 750, 1000, 1200], $
/Fill, /Overplot, Map=map, C_Colors=Bindgen(4)+1B
cgColorBar, Range=[500, 1200], Divisions=3, $
Position=[0.6, 0.1, 0.9 , 0.15], NColors=4,Bottom=1
END

Code I used to create the plot:

IDL> cgPS_Open, 'test.ps'
IDL> .Run ps_example
IDL> cgPS_Close, /PNG, DELETE_PS=0

Cheers,

David
